BRITAIN, CONNECTICUT, A. OOBIORA- SAFETY-RAZOR.

Patented Oct. 21, 1913.

Application filed Hatch 11, 1918. Serial No. 753,491.

- a citizen of the United States, residing at New Britain, Hartfordcounty, State of Connecticut,-have invented certain new and usefulImprovements in Safety- Razors, of which the following is a full, clear,and exact description.

This invention relates to so-ealled safety razors, and is designed toprovide a simple and efficient structure of this character.- Anefiicient blade-clamping means is'provided which will afford readyaccess to the blade and razor parts when it is desired to remove theblade or cleanse the razor.

It is my aim to provide an effective structure of this character whichreadily lends itself to afford substantial economies in manufacture.

To this end my invention consists in the relative arrangement andcombination of parts more fully described in the followingspecification, taken in connection wlth the accompan ing drawingsforming part thereof and il ustrating preferable embodiments of theinvention.

In these drawings: Figure 1 is a view in end elevation of the invention.Fig. 2 is a view in front elevation, on an enlarged scale, of thepartsshown in Fig. 1. Fig.3 is a top plan view of the parts shown in Fig. 2,the clamping member being shown in bladereleased position in dottedlines.

Referring to the drawings by numerals, 11 designates the usual handleand 12 the blade supporting plate rigidly secured thereto and incliningdownwardly at an angle, this plate being suitably notched or recessed atits forward edge, as at 13, to provide the usual guard, and intermediateits forward and rear edges and at its sides, is provided with anintegral upwardly and inwardly extending lu 14 w se inward extensions 14roject from the upper face of the supportlngplate. Adjacent its rearedge, the late 12 is provided with a longitudinal 0 set 15 to which theoffset end 17 of a clamping plate 16 is pivotally connected by anysuitable means. This clamping plate 16 extends substantially the entirelength-of the supporting plate 12, and its free end is provided wit afinger piece extension 18 projecting out beyond the edge of the plate12. The offset 17 of this clamping plate is positioned adjacent its rearedge, as

. and also preferabl is the finger piece 18, and the bod of the clampingplate is formed to exten in over the face of the supporting plate 12' toa pointpreferably beyond the inward extensions 14. The plate 16 is ofspring material pivoted to bring its edge in a plane shghtly above theunder faces of these extensions 14. The thickness of this-clampin platehears such relation to the distance ietween the under face of theseinward extensions 14 and the top face of a razor blade firmly seated onthe plate 12 that when this clamping plate is swung inwardly from itsupper edge, it will frictionally engage the abutment surfaces formed bythe under faces of these lug extensions 14* and will be frictionallyheld thereby in tight clamping engagement with the upper face of therazor blade. In order to make this engagement a secure one, I prefer toform the under faces of these extensions 14* with a slight bevel so thatthe clamping plate 16 will be firmly wedged into clamping engagementwith the upper face of the razor blade 19 whose forward cutting edgerests against the stop shoulders 20 at tlie forward guard edge of thesupporting ate.

It will hardly be necessary to describe the operation of the razor indetail, as the looking function of the clamping plate 16 will beobvious, and the unclamping operation merely requires suflicientrearward prewure against the plate to withdraw it from frictionalengagement with the under face of the inward extensions 14. so that theclamping plate 16 may be swung to the position shown in dotted lines inFig. 3 to permit the removal of the razor blade.

The rovision of Wedging means affords a ver e cient frictional clampwhich will maintain the razor blade in adjusted position during use. Byproviding a pivot point for the clamping arm which is offset from theplane of the supporting plate, the clamping arm may overlapand engagesubstantially the entire length of the razor blade and in addition itmay be swung absolutely clear of the razor blade tofacilitate rangementof parts within the spirit of the invention and the scope of theappended claim.

What I claim therefore, and desire to secure by Letters iPatent is:

In a safety razor, a handle, a blade-supporting plate rigidly connectedthereto at an angle and having a guard at its forward edge and stopshoulders adjacent said edge for a razor blade, said plate also having alongitudinally extending olfset adjacent its rear edge and havingintegral lugs extendjacent its rear edge to said longitudinal ofiset andarranged to extend longitudinally of said plate for substantially itsentire length and m a plane parallel therewith, said arm being arrangedto swim toward and. from the rear edge of said ate and being constructedto engage with its u per face the beveled under faces of said ugswhereby the under face of said arm may be wedged in frictional clampingengagement with the upper face of a razor bla e seated over saidsupporting plate.
